By Park Si-soo Which company offers the fattest paycheck in South Korea? Samsung Electronics? It is a high ranker, but slightly shy of the top. Hyundai Motor? Lower than Samsung. Naver? Not in sight. According to recruiting information website Incruit, oil refiner S-Oil topped the list of 30 best-performing listed companies in terms of sales in the first half of this year, with an average six-month per capita salary of 76.67 million won ($67,720). Doubling the figure would be the company's expected average annual salary for this year. Next was another oil refiner SK Innovation (72 million won), SK Telecom (69 million won), KB Financial Group (63 million won) and Shinhan Financial Group (63 million won). Samsung Electronics ranked 14th with 43 million won. The average six-month salary of the top 30 companies was 44.58 million won. The list and figures were based on companies' half-year reviews published by the Financial Supervisory Service, said Incruit. Last year's highest-paying company was, again, S-Oil with an average annual salary of 120 million won, including year-end bonuses. Samsung Electronics was second with 1.17 million won -- the tech giant is well known for its handsome year-end bonus. SK Innovation was third with 111 million won, GS Caltex (108 million won), SK Telecom (106 million won), LG International (100 million won), Kia Motors (93 million won), Hyundai Motor (92 million won), Samsung Life (91 million won), LG Chem (90 million won) and Samsung C&T (90 million won).
